What is the most pathetic, or outrageously bad piece of dialogue you've ever heard in a TV series?

There's a scene in Walker Texas Ranger that I happened to catch when I was ~10 years old. Walker, the Texas Ranger, is surrounded by a dozen gangsters. Each gangster has either a pistol or a light sub-machine gun. They are seconds away from turning him into swiss cheese when he speaks up and says something like: "be a man, take me on mano y mano". The gangsters all look at each other and proceed to silently agree. Then proceeds 5 minutes of - one by one - each gangster getting their proverbial ass handed to them. As each gangster tossed aside their gun, it got more and more absurd that they wouldn't realize he had a black belt and simply shoot him; ala Indiana Jones in the sword fight.

Anything William Shatner lol
